My invention relates to soluble supports or cops for yarns, which, in the usual process of manufacture in the form of packages, are subjected to processes such as bleaching and dyeing.

Heretofore metal cops have been predominant, and aside from their relative expense, have been unsatisfactory, because of chemical reaction with the dye bath and the formation of rust upon the tube.

For instance, the ordinary practiceof employing springs with or without a stocking has been found in many instances to result in staining of the yarn package, due to the fact that foreign matter collects about the springs and on the stockings.

With the present invention, however, the materials used are soluble in the dyeing or bleaching bath, and I have found that a cop tube formed of such materials would not only result in perfect packages, but the materials themselves will exert a very favorable action upon the bath, and in the case of a dye bath, act as a retarder or prevent the solution from being too active.

In carrying out the invention, I form a support or cop tube of any usual shape, such L I may either mold it or form the support of pliable material.

In any event, the materials of which the cop tube or support are formed, will be soluble in the dyeing or bleaching bath.

The materials which are used for forming the tube or cop may comprise vegetable or animal glue, vegetable or animal gelatin, gum tragacanth, gum acacia, or gum arabic, all of which are soluble in the usual dyeing or bleaching bath.

In addition to these materials, may use soap of vegetable or animal composition, and also a salt, such as sodium chloride.

I may form the cops or supports wholly of any of the above materials, or I may combine one or all of them in various ways, as desired.

If a binder is required in connection with the above materials, I use deXtrine or dextrose, and when it is desired that the cone have 'ing bath is to the yarn, whether it be cotton, wool, rayon,

' Moreover,

additional pliability, I mix glycerine with any one or more of the said ingredients.

- The proportions employed of any one or more of the several ingredients may be varied- I desired shape or contour.

Referring to the use ofsalts, or soap, these two materials exert a very desirable effect,

in that they produce a level dyeing of the yarn package.

All the ingredients mentioned, however,

exert a retarding efiect upon the dye bath, and in the case of a bleaching operation, go into solution without any harm to theyarn under treatment. I have found that by using a cop or support formed of any one of the several ingredients above mentioned,.or variousmixtures'of them, the dyeing orbleachfavorably affected without harm or other materials.

IN here the copor tube'is made'up from sheets, as above set forth, such sheets Will be sufficient thickness and them to be rolled or bent around a core or winder spindleto thedesired configuration,

to receive and support a yarn package.

- I may make the support or cop tube solid,

. or-I may make it hollow, in the usual manner. the hollow tube may be perforated inacco'rdance'with the usual practice.

Thenyarn having been placed upon the support or cop tube is attached to the ordinary rack spindle used invdyeing andbleaching processes. 7

In the-subsequent 'emersion or treatment of the package in the bath, the tube will go into solution. As stated, the ingredients above mentioned will act as retarders in the case of dye baths, in that they'retard the acthe plasticity to permit rob tion of the dye and keep the solution from going on too fast.

In the case of bleaching operations, there will be no opportunity for the collection of foreign matter about the tube or the formation of rust, so that a beautifully dyed package will be the result.

While the ingredients mentioned for producing the soluble cop tube are not essential to the bleaching or dyeing operation, they do accomplish the advantageous results set forth, and, as heretofore stated, may also be the carrier for Various chemicals which it is desired to employ for specific dyeing or bleaching operations.

here ordinary sodium chloride, or other granular salts, is employed, one of the binders above mentioned will be usually incorporated, although this is not essential.

The invention eliminates the disadvantageous results occasioned by the employment of the usual metallic tubes, or tubes of paper and Wood, and aside from being a cheaper process and producing a more perfect yarn package, free from defects, the use of the soluble materials actually aids the dyeing and bleaching operation.

I claim 1. A support for a yarn package soluble in the bleaching and dyeing fluids to which the yarn is subjected, and comprised of an ingredient which will act as a retarder for the d e.

2. A cop tube for a yarn package soluble in the bleaching and dyeing fluids to which the yarn is subjected, and comprised of an ingredient which will act as a retarder for the dye.

3. A perforated support for a yarn package soluble in the bleaching and dyeing fluids to which the yarn is subjected and comprised of an ingredient Which will act as a retarder for the dye.

4:. A perforated cop tube for a yarn package soluble in the bleaching and dyeing fluids to which the yarn is subjected, and comprised of an ingredient which will act as a retarder for the dye. V

5. A support for a yarn package formed of moldable material soluble in the bleaching and dyeing fluids to which the yarn is sub jected, and comprised of an ingredient which will act as a retarder for the dye.

6. A cop tubefor a yarn packageformed A of moldable material soluble in the bleaching and dyeingfiuids to which the yarn is subjected, and comprised of an ingredient which Will act as a retarder for the dye.

In testimony whereof I have hereunto set my hand.
